TROLLEY-POLE.

SPECIFICATION forming part of Letters Patent No. 708,559, datedSeptember 9, 1902.

Application filed December 8,1900. Serial No. 39,215. (No model.)

To ztZZ whom it may concern.-

Be it known that 1, CHARLES D. JENNEY, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Trolley Poles, ofwhich the following is a specification.

The objectof my said invention is to produce the device usuallydenominated a trolley-pole for electric cars, &c., which shall embody inits own structure means whereby it will yield as the relation of the caron which it is mounted to the conductor-wire varies, so as to maintainthe contact between the contact devices and the wire continuouslyinstead of providing separate means, as is common.

A pole embodying my said invention will be first fully described and thenovel features thereof then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof,and on which similar reference characters indicate similar parts, Figure1 is a side elevation of a streetcar and a fragment of a conductor-wire,said street-car being equipped with a trolley-pole embodying my saidinvention. Fig.2 is a detail view, on an enlarged scale, partly inelevation and partly in section, of that portion of the pole andimmediately-adjacent parts which particularly embody said invention;Fig. 3, a top or plan view of the bowllike socket wherein the lower endof the pole is secured, and Fig. 4 a plan view of the clamping-washerwhereby the form of spring illustrated as constituting a part of thepole is secured in place in the bowl on top the car.

In said drawingstho portions marked A represent a street or other car, Bthe ordicured within a bowl-like socket 7 to the deckplank D on top thecar. The part 6 is preferably a coiled spring, and the lower end of thepart 5 enters into said spring and is there held in any suitable manner,as by a clamping-bolt 4. The spring portion at the other end is heldwithin the bowl-like socket by means of a washer 8 and a bolt 9. Saidbowl 7 is formed flaring and rounding, so as to support the springportion of the pole as it bends in any direction in doing its work.Openings are formed through its bottom, so that no water will be heldtherein.

As will be readily seen, a pole of this character having a suitableflexible portion will yield in any direction, and the use of heavycomplicated yielding supporting devices is wholly avoided, while allnecessity for pivotal connections is obviated, as the pole will bend aswell in one direction as another, and thus is capable of sidewise aswell as front and rear inclinations without being revolved.

Having thus fully described my said invention, What I claim as new, anddesire to secure by LettersPatent, is

1. The combination of an electric car, an overhead conductor, a poleextending from said car to said conductor and embodying in its structurea spring whereby it may yield in any direction, and a bowl like socketformed with outwardly-curved sides Within which the spring-like lowerend of said pole may be secured. I

2. The combination of an electric car, an overhead conductor, a polecarried by said car and extending to said conductor, the lower endwhereofis in itself a spring, a bowl-like socket having outwardly-curvedsides secured to the car into which said spring-like lower end of thepole enters, and a clamp washer and bolt whereby said spring-like lowerend of the pole is secured within said socket.

In witness whereof I have hereunto set my hand and seal, atIndianapolis-Indiana, this 4th day of December, A. D. 1900.
